I really like the video It's Halftime In America. Clint Eastwood did a good job. On my local news station (KSBW) they did a interview with him about the controversial commercial and Clint Eastwood said that he did not earn a dime for making that commercial and any money that he earned he gave it all to charity. The views Clint Eastwood expressed were all his own. Way to go Clint Eastwood.

What if you watch the same video twice, sometimes the same one pops up twice, will you get double credit ?

Yes you will get credit for both On the occasion where you keep watching a video and still don't receive credit and others are having the same problem it's usually the video, if not than it could be the browser/video
